Granite yog hom pob zeb ntau tshaj plaws ntawm qhov chaw.Nws tsim ib qho ntawm cov kev hloov pauv ntawm cov av loj heev nyob rau hauv cov nqe lus ntawm nws cov tshuaj muaj pes tsawg leeg thiab yog ib qho tseem ceeb cim uas txawv lub ntiaj teb los ntawm lwm cov ntiaj chaw.Nws tuav lub secrets ntawm txoj kev loj hlob ntawm lub continental crust, evolution ntawm mantle thiab crust, thiab nrog mineral kev pab.
Nyob rau hauv cov nqe lus ntawm genesis, granite yog ib tug tob intrusive acidic magmatic pob zeb, uas yog feem ntau tsim raws li ib tug pob zeb los yog strain.Nws tsis yooj yim kom paub qhov txawv ntawm granite los ntawm nws cov tsos;Nws qhov tshwj xeeb yog nws cov xim daj ntseg, feem ntau yog xim nqaij-liab.Cov zaub mov tseem ceeb uas ua rau granite yog quartz, feldspar thiab mica, yog li feem ntau cov xim thiab luster ntawm granite yuav txawv nyob ntawm feldspar, mica thiab cov ntxhia tsaus.Hauv granite, quartz suav txog 25-30% ntawm tag nrho, nws muaj qhov zoo li lub khob me me nrog lub ntsej muag greasy;poov tshuaj feldspar account rau 40-45% ntawm feldspar thiab plagioclase 20%.Ib qho ntawm cov khoom ntawm mica yog tias nws tuaj yeem muab faib ua nyias flakes nrog ib rab koob raws lub deconstruction.Qee lub sij hawm granite yog nrog los ntawm cov zaub mov tsis zoo xws li amphibole, pyroxene, tourmaline thiab garnet, tab sis qhov no tsis tshua muaj lossis tsis yooj yim pom.
Qhov zoo ntawm granite yog qhov zoo, nws yog homogeneous, tawv, tsis muaj dej nqus, lub zog ntawm cov pob zeb tuaj yeem ncav cuag 117.7 txog 196.1MPa, yog li nws feem ntau suav tias yog lub hauv paus zoo rau cov tsev, xws li Peb Gorges, Xinfengjiang, Longyangxia, Tenseitan thiab lwm cov dams hydroelectric yog ua los ntawm granite.Granite kuj yog lub tsev pob zeb zoo heev, nws muaj zog zoo, thiab muaj zog compressive, me porosity, tsis tshua muaj dej nqus, ceev thermal conductivity, zoo hnav tsis kam, siab durability, Frost tsis kam, acid kuj, corrosion kuj, tsis yooj yim rau huab cua. , yog li nws feem ntau yog siv los tsim cov choj piers, cov kauj ruam, txoj kev, tab sis kuj rau cov tsev masonry, laj kab thiab lwm yam.Granite tsis yog tsuas yog muaj zog thiab siv tau, tab sis kuj muaj qhov zoo nkauj nrog cov ces kaum zoo nkauj, yog li nws feem ntau siv rau hauv kev kho kom zoo nkauj sab hauv thiab suav tias yog cov pob zeb zoo nkauj zoo nkauj.
Granite tsis yog ib hom pob zeb, tab sis muaj ntau yam sib txawv, txhua qhov qhia txog cov khoom sib txawv nyob ntawm cov khoom sib xyaw.Thaum granite yog tov nrog orthoclase, nws feem ntau tshwm liab.Lwm cov granites yog grey los yog, thaum metamorphosed, tsaus ntsuab.
